ALBERT H. WATKINS, OF BOSTON, MASSACHUSETTS.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 239,995, dated April 12, 1881.

Application tiled February 1, 1881. (No model.)

To all whom it may concern:

Be it known that I, ALBERT H. WATKINs, of Boston, in the county oi' Suffolk and State ot' Massachusetts, have invented anew and uscful Improvement in Vapor-Burners, of which the following is a specification.

This invention relates to burners in which hydrocarbon uids are vaporized and mixed with air to produce gas, and particularly to burners having rings between which are the burner-tip and illuminating-Haine, also used for heating purposes.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure lis a vertical section of a vapor-burner embodying my invention. Fig. 2 is an end elevation of the same. Fig. 3 is a plan view.

A is the burner-tip, made separate from the burner, and dropped into an opening` made for the purpose in the mixing-chamber, in which it is held firmly by the set-screw D.

B is the mixing-chamber, of inverted conicocylindrical form, the intention being to provide a mixing-chamber which shall be larger at the top than at the bottom. This may be accomplished by graduating it, as shown--z' e., inclining its sides outwardly toward the top, or by drilling it out in two or more sizes, the larger size at the top, but the shape shown is considered the best.

O C are two rings, integral with the walls of' the chamber B, and set at an acute angle to each other, so as to ilare upward and outward, as shown. are not more wings or plates, but rings, allowing air to pass through their open centers horizontally to the llame.

The base of the burnerv is constructed asi usual, E being the generator, F the lighting or drip cup, Gr the needle-pointed regulatingscrew, H H the air-holes, and J the supplytube, packed as usual.

A difficulty in vapor-burners is the liability of the illuminating-dame to blow when the size of the dame is increased by withdrawing the regulating-screw G. Different devices have been employed to overcome this difficulty, such as plugs, screws, and dampers in the side It will be noticed that the parts C4 of the mixing-chamber, and rings and guides around the air-holes; but these all require adjusting to the different sizes of the illuminating-flame to produce the proper combustion. This difficulty is entirely overcome without aid from any of the devices named, by means ot' lnyinverted conico-cylindrical mixing-cham- 'ber B, which allows the light to be increased from small to large with perfect combustion and without blowing.

The tip A, being easily detachable by means of the set-screw D, can be removed and the chamber B cleaned, and a new tip inserted, it' desired. v

l am aware that rings have been used on vapor-burners, generally brazed upon the side of the burner-tube, but not flaring rings. I arrange mine to ilare, as shown, in order to allow of the natural vibration ot' the i'lame without interfering with it. The close proximity of the base of the tlame (which is the heating part) to the rings imparts suicient heat to the burner to vaporize the hydrocarbon fluid` in the generator.-

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a vapor-burner, the combination, with a mixing-chamber, ot the iiaring rings O C, having their upper portions farther apart than their lower'portions, substantially as and for the purpose set t'orth. y

2. In a vapor-burner, the combination, with the mixing-chamber B and daring rings (l, ot the removable tip A, adapted to be held in place by the set-screw D, substantially as speciiied. y

3. The herein-described improved vaporburner, consistingot' the generator E, provided with air-holes H, regulating-screw G, mixingchamber B, tip A, and daring rings OO, constructed and arranged substantially as and for the purpose described.

ALBERT' H. wA'rKINs.
